Catskills trout locked into Green Drake season as streams drop to summer lows

What's Biting

What's Next

With both Catskills gauges showing summer-low flows, 65.4 cfs on the East Branch Delaware and 10.4 cfs on the Beaverkill, conditions over the next few days favor the technical, clear-water approach that defines early summer on these streams. Absent a significant rain event, flows will likely hold steady or ease further as the region settles into its summer pattern. That means fish compressing into the deepest, shadiest lies, so work structure deliberately rather than covering water.

The Green Drake window is the immediate priority. Per Flylords Mag's current coverage, the hatch is drawing fish to the surface in afternoon and evening sessions, with anglers matching the dun reporting brook trout responding well. This hatch typically runs one to two weeks on the Catskills, peaking in late May through mid-June. If you have not hit it yet, this week likely offers the back half of the window. Fish the slow, flat pools in the last two hours of daylight; the Last Quarter moon means dark evenings with minimal competing moonlight, ideal conditions for coaxing big browns up on large dry flies.

Once the Green Drake push winds down, typically by the third week of June, the focus shifts to sulphurs, Light Cahills, and Blue-Winged Olives that sustain Catskills fishing through summer. MidCurrent's recent Tying Tuesday laid out a full surface-to-film toolkit: CDC emergers in the film, buoyant attractor dries in fast seams, and subsurface patterns for fish that are rising but refusing the top. That coverage translates directly to the transition window ahead, especially on flat, clear water like the Beaverkill's signature pools.

For the weekend, nymph anglers should heed Gink and Gasoline's recent reminder: in low water, trout compress into the deepest slots and undercut banks, and running enough weight to reach the bottom of a two-foot pool separates a blank day from a productive one. Tight-line and Czech methods suit the Beaverkill's riffle-and-pool structure well at these flows. Watch for afternoon thunderstorms, common in June across this terrain, which can briefly spike flows and suppress fish, then trigger a short active window as the water clears.

Context

Early June in the Catskills marks the peak of the dry-fly calendar: the transition point between the spring Hendrickson and March Brown flights and the long sulphur-and-Cahill summer that follows. The Green Drake hatch, documented by Flylords Mag this week, is the signature emergence of this window and historically one of the most anticipated events on the Beaverkill and Delaware system. It typically arrives in the last week of May and runs through mid-June, with the peak shifting several days depending on water temperature and elevation.

At 65.4 cfs on the East Branch Delaware (gauge 01413500) and 10.4 cfs on the Beaverkill (gauge 01415000), flows are consistent with a normal early-June drawdown following spring snowmelt and runoff. Both readings indicate typical wade-friendly summer-low conditions for this date, not a drought or flood event. The Beaverkill at 10.4 cfs is toward the lower end of its comfortable wading range, so wet-wading is possible but expect thin conditions in the riffles.

Trout Unlimited's current coverage on brook trout is a timely reminder: the native brookies of the upper Catskills and Adirondack headwaters represent the region's oldest fishing tradition, and early June is their prime window before summer heat pushes them deeper into cold, spring-fed reaches. Anglers targeting brookies should focus on upper-elevation streams and tributaries rather than the main stem, where summer temps arrive first.

No direct on-the-ground reports from local Catskills shops or a state agency source were available in this reporting cycle. Current conditions are grounded in USGS gauge data and broader fly-fishing community coverage; local shop intel would sharpen the picture considerably.
